Very interesting and promising. However I think it is a bad idea to
make it standard behaviour in any CAD program. They should stick with
what they have I recon and only provide this new file format for users
who know what they want.
My reason for saying that is for people who don't have their filesystem
optimised for this and generally don't bother about filesystems really.
For example I never bothered finetuning my ext2 filesystem as it is very
low on my priority list and would require lots of analysis, I just never
found the time. This means that my filesystem is just the standard
generated by Debian, which happens to have a block size of 4Kb. Now
this last small detail has quite some inpact on this fileformat as it
potentially has thousends of small files way smaller then the block size
of the average filesystem, makeing whole the drawing an absolute huge
size on disk.
Secondly, and less important, it is dangerous to just rely on the undo
of the filesystem. Once more this is for users who don't have theire
Don't get me wrong. I think it is a great idea and would love to see it
being used to test it in actual industial type use. See how it performs
in real life.
Just my thoughts...
